运行selenium remotedriver时出现带有NativeConstructorAccessorImpl.newInstance0的SessionNotCreatedException错误 [英] Error SessionNotCreatedException with NativeConstructorAccessorImpl.newInstance0 while running selenium remotedriver

问题描述

我正在运行以下内容但收到错误

I am running the following but getting the error

public class base
{
    public static WebDriver driver;

    public static void main(String[]  args) throws MalformedURLException, InterruptedException
    {
        System.setProperty("webdriver.chrome.driver", "C:\\code\\lib\\browser drivers\\chromedriver.exe");

        String URL = "http://www.google.com";
        String Node = "http://localhost:4444/wd/hub";
        DesiredCapabilities cap = DesiredCapabilities.chrome();
        cap = DesiredCapabilities.chrome();
        cap.setPlatform(org.openqa.selenium.Platform.WINDOWS);


        driver = new RemoteWebDriver(new URL(Node), cap);

        driver.navigate().to(URL);
        Thread.sleep(5000);
        driver.quit();
    }       
}

显示错误如下：

Exception in thread "main" org.openqa.selenium.SessionNotCreatedException: Unable to create new service: ChromeDriverService

有人可以请帮助

推荐答案

请执行以下操作并重试。

Please do the following and retry.

确保路径 C：\\code\\lib\\ browser drivers \\chromedriver.exe 已添加到您的％PAT运行节点的计算机上的H％变量。这将确保selenium uber jar可以找到chromedriver二进制文件的位置。

Ensure that the path C:\\code\\lib\\browser drivers\\chromedriver.exe is added to your %PATH% variable on the machine in which you are running the node. This would ensure that the selenium uber jar can find the location of the chromedriver binary.

System.setProperty（webdriver.chrome .driver，C：\ code \lib \browser drivers \chromedriver.exe）;

此机制仅在您执行时使用

This mechanism should be only used when you are doing

ChromeDriver driver = ChromeDriver（）

由于您正在使用selenium网格，因此您在此处理多个JVM。

Since you are working with a selenium grid, you are dealing with multiple JVMs here.

System.setProperty（）只会影响当前的JVM（在本例中是您的测试），但是实际的浏览器在另一个JVM（运行selenium节点的JVM）中分离出来。

System.setProperty() will affect only the current JVM (which in this case is your tests), but the actual browser gets spun off in a different JVM (the one that is running the selenium node).
